Title: A new or improved mixing device for delivering water mixtures or solutions
IPC: C02F1/68
Filed: 1956-12-05
Abstract: 817,679. Apparatus for dosing liquids. LAMBTON, C. W. March 25, 1957 [Dec. 5, 1956; Jan. 14, 1957], Nos. 37239/56 and 1408/57. Class 86 [Also in Group I] In a device for introducing a quantity of perfume, soap or other chemical substance into a water supply, a closed container 9 for the substance is disposed in a sleeve 7 having slidably mounted therein a rod 14 which, when moved to apply pressure to the container 9, will rupture it. The sleeve 7 is slidably mounted in a cylindrical wall 5 provided in a housing 1 through which the water flows, and radial drillings 16 in the wall 5 are arranged to pass part of the water through the cylindrical wall and into and out of the sleeve 7. The degree of mixing can be controlled by varying the angular position of the drillings 16 relative to the direction of water flow, the wall member 5 being rotatable for this purpose. In a modification, Fig. 4, the container, disposed in a sleeve 23, is pierced by a rod 31 provided with passages 40, 41 through which the substance is discharged into the water stream. Due to the nature of the container material, a sealed joint is automatically provided between the container and the rod 31, and the mixing may be interrupted if the rod is displaced to a position in which the passage 41 is within the container. Alternatively the piercing means may produce one or more punctures in the container and then be withdrawn to allow discharge of the substance.

Title: Improvements in embossing and like presses
IPC: B30B1/04
Filed: 1928-12-18
Abstract: 326,774. Brecknell, W. H. Dec. 18, 1928. Presses, mechanical.-In presses for embossing, &c. the movement of a presser member towards the bed is effected by means of a beam which is in pivotal contact with the presser member throughout its length and is given a combined movement of rotation and translation. The bed 3, Figs. 1 and 2, comprises a steel block of rectangular section disposed between the lower ends of frame sides 1, 2 formed of angle or T-section iron with forwardly extending horizontal portions. The presser member 7 is formed similarly to the bed 3 and is guided vertically between front and rear guide-plates 9, 8 secured between the frame sides. Helical springs 18 pivoted on studs 20 on the front of the presser member 7 are formed with end extensions which bear upon the front guide plate 9 and studs 19, 21 and tend to retain the presser member in its raised position. The beam 10 which effects the movement of the presser member is pivoted at its ends to the upper ends of a pair of links 4 which are pivoted to bolts or integral studs 5 extending from the ends of the bed 3 through the frame sides 1, 2, where they are secured by nuts 6. The beam 10 is made of steel, of square or other section having a V-shaped bottom edge bearing upon the presser member 7, where pairs of pins 11, 12 on the one member engage corresponding recesses in the other member to prevent relative sliding. An operating-lever 13 is connected near its end to a pair of links 15 mounted on a shaft 16 journaled between the frame sides 1, 2, the end of the lever being forked to enable it to be pivoted to a lug on a plate 17 secured on the outer face of the beam 10. In operation, the lever 13 is pulled forwardly, thereby imparting the combined movemen of rotation and translation to the beam, the maximum pressure being attained when the points of pivotal connection between the lever, beam, and bed are in alignment, the links 4 being then vertical. Eccentric bushes 22 or similar means may be provided to enable the pivots 5 to be adjusted. The connection between the lever 13 and the beam may be modified by fitting the end of the lever within a recess in the beam and pivoting it on a shaft which passes longitudinally through the beam and may form the pivotal conection to the uper ends of the links 4. The horizontal parts of the frame sides 1, 2 may be shaped to provide runners for a sliding platen of the kind described in Specification 277,529, [Class 100 (ii), Printing processes &c.].

Title: Improvements in or relating to radar stations
IPC: G01S13/524
Filed: 1957-12-02
Abstract: 845,326. Radar. TELEFUNKEN G.m.b.H. Dec. 2, 1957 [Nov. 30, 1956], No. 37421/57. Class 40(7). In a pulse radar system, in order to render the elimination of fixed targets more complete, the directional beam is caused to occupy a series of azimuthal positions, in each of which it is stationary, the movement from one position to the next being almost instantaneous. The beam is formed by a dipole located near the focus of a reflector and the complete assembly rotates continuously about an axis between the reflector and dipole. The dipole also rotates continuously, in the opposite direction, about a second axis and the beam, due to this dipole, is maintained in a fixed azimuthal direction. After the system has rotated a predetermined angle, the dipole is short-circuited and a second dipole, angularly displaced from it, is substituted, the effect being to cause the beam to move instantaneously in azimuth to a near fixed position. As shown, Fig. 3, the mirror 12 and dipoles 13-20 rotate continuously about an axis between the dipoles and mirror. The dipoles rotate in the opposite direction about point 30. The fixed strip 31 short-circuits all dipoles except that nearest the mirror. In an alternative form, not shown, the dipoles are replaced by slot radiations fed from a cavity resonator.

Title: An electronic switching circuit arrangement
Inventor: SNIJDERS ANTONIE
IPC: H03K19/12
Filed: 1952-07-09
Abstract: 780,002. Discharge-tube coincidence circuits. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. July 9, 1952 [July 12, 1951], No. 37887/56. Divided out of 780,001, [Group XL (b)]. Class 40 (6). An electronic switching arrangement comprises a plurality of rectifiers with all their anodes or all their cathodes connected to a common point which is connected respectively to the positive or negative terminal of a source of potential, associated with an equal or lesser number of switching units each having an input terminal and two output terminals producing potentials corresponding to or inverted relative to the input potential, the free terminal of one of the rectifiers being connected to an output and the inputs of other rectifiers being connected to output terminals of the switching units, the arrangement being such that upon the application of predetermined potentials to the inputs of the switching circuits, a voltage is obtained at the free output terminal of said one rectifier. In the arrangement shown in Fig. 1, the anodes of the rectifiers G1, G2 ... G7 are connected to the common point P and thence through a resistor R to the positive side of a voltage source V whose negative pole is connected in common to earthed terminals T1, T2, T3 of electronic voltage switching units S1, S2, S3, as described in Specification 780,003, which in response to an input voltage at I1 ... produce a voltage of the same polarity at U1 ... and an inverted voltage at U<SP>1</SP>1. In the simplified arrangement shown in Fig. 1, the switching arrangement S3 produces a negative output at terminal U3 of the unit S3 except in the case in which I1 is positive and I2 is negative so that positive outputs at U1 and U<SP>1</SP>2 applied to the rectifier network allow a positive potential to be applied via G6 to the input of S3. In a modification, Fig. 2 (not shown), the " P ", or common, points of two separate positively poled circuits, such as those shown in Fig. 1, are connected by oppositely-directed rectifiers to the " P " point of a negatively poled arrangement associated also with an input trigger circuit, such as S1, S2, and connected to an output switching unit such as S3 of Fig. 1. The purpose of this arrangement has not been clearly described, but appears to be such that an output of specified polarity is obtained at respective output terminals in response to predetermined combinations of pulses at five input terminals of which one is associated with the negatively poled arrangement, whilst the two positively-poled arrangements are controlled by three input terminals and one input terminal. U.S.A. Specification 2,535,303 is referred to.

Title: Improvements in and relating to the chilling of foodstuffs and the like
IPC: F25D3/10
Filed: 1956-12-11
Abstract: 839,380. Cooling foodstuffs; refrigerating. MORRISON, W. L. Dec. 11, 1956, No. 37889/56. Class 29 Material such as foodstuffs either packaged in pervious containers or unwrapped and preferably pre-frozen is chilled for storage and transport in a container 1 by a low-temperature evaporating refrigerant, e.g. liquid nitrogen, at atmospheric pressure, some liquid refrigerant being left in contact with the material after the chilling. The container 1 has a top closure 2 beneath which is a refrigerant spray network 4 discharging into a pad 3 from which the refrigerant flows on to the material 6, the evolved gas leaving through a pipe 10. After chilling, the pipe 10 is closed by an insulating plug. As shown in Fig. 1, gaseous refrigerant is withdrawn from container 1 through pipes 10, 12 by an impeller 13 which supplies it to a gaseous refrigerant reservoir 14. The gas then flows through pipe 15, a heat exchanger 16 and pipe 17 to first compressor 18. The compressed gas is cooled by water-cooled heat exchanger 20, is further compressed by compressor 22 and further cooled by water-cooled heat exchanger 24 and heat exchanger 16. The gas then operates expansion motor 27 in part driving the compressors and thus liquefies partly and flows to separator 29. The separated gas flows through pipe 36 to impeller 13 while the liquid flows to receiver 31 whence it is pumped by pump 34 to container 1. There may be more than two compression stages. On starting up, some refrigerant may be vented from the container to displace air therefrom. Alternatively, the air may be vented from the refrigerant circuit when necessary. Vents may be provided in pipe 12 and receiver 31 for charging and discharging refrigerant into and from the system. Specification 798,769 is referred to.

Abstract: 892,161. Seaming non-metallic sheet material. FLAX, V. Nov. 10, 1959 [Nov. 10, 1958], No. 38150/59. Class 42 (1). [Also in Croup XVII] In packaging apparatus of the type where a plastic tube is filled with a liquid to be packaged and is then sealed at intervals transversely to form a multi-compartment package, the sealing means permit flow of liquid between compartments during part of the sealing operation to allow equalization of internal pressures. One jaw 4 may be serrated so that welding takes place initially at the serration peaks and heat is then applied until the plastic flows to fill the gaps. A heated plain or serrated roller may seal progressively by rolling across the tube transversely. Heat may be direct or produced by high-frequency current. The invention is said to be particularly applicable to thin-walled tubes. A serrated jaw may be formed by blocks 26 separated by insulating strips 27, the assembly being removably clamped in a block 24. The jaws or roller may be formed to produce oblique, angled or other shaped seams.

Abstract: 1,061,215. Mechanical relays. ELLIOTT BROS. (LONDON) Ltd. Sept. 16, 1965 [Sept. 18, 1964], No. 38313/64. Heading F2X. An input member 4 and an output member 9 which are angularly movable are coupled by means including a piezo-electric element E deflectable in response to applied potentials from a non-deflected to a deflected condition, the arrangement being such that in changing from one condition to the other the element brings the input and output members into angular registration, the coupling means being such as to allow at least some free relative angular movement of the members when the element is in one condition, there being provided means 17 for preventing movement of the input member while the two members are brought into registration. Normally, the input and output members are locked together by engagement of a rod 13 in the V-slot of a member 14 until a potential difference is applied to the element E by deflecting a brush 15 into engagement with a slip-ring 16. This withdraws the rod 13 from the V-slot and enables the input member 4 to take up a new angular position which is also taken up by the output member when the brush 15 is disengaged from the slipring and the rod 13 is restored to the V-slot. The braking means 17 includes piezo-electric elements which are energized when the brush 15 is disengaged. In a modification, axially projecting pins on the input and output members are positioned between a pair of parallel piezoelectric strips which diverge when energized to permit the input member to move angularly. The piezo-electric strips may be lead zirconate bimorphs 1 inch long by 0À1 inch wide and 0À02 inch thick with an actuating potential of 220 volts. The deflection is 0À12 inch at a frequency of 4 to 10 c/s.
